Abstract: Powder (14) is filled in an axially elongate powder filling space (1) defined in a flexible pressure tube (25, 225, 245, 325, 525), and the pressure-bearing surface of the flexible pressure tube (25, 225, 245, 325, 525) is pressurized with a pressurizing fluid (7), from a wall portion of the pressure tube (25, 225, 245, 325, 525) which corresponds to a localized region of the powder filling space progressively toward another wall portion of the pressure tube (25, 225, 245, 325, 525) which corresponds to an end of the powder filling space (1), until the pressure-bearing surface of the pressure tube (25, 225, 245, 325, 525) is pressurized in its entirety, for thereby compacting the powder (14), in the powder filling space (1). Therefore, air in the powder (14) is progress­ively squeezed toward the end of the powder filling space (1) where the air can be discharged out. No air thus remains trapped in the powder (14), and a formed product is prevented from being damaged, which enables to produce elongate products.

Abstract: An element which in use emits heat, e.g. a line feed motor (LF) for a printer, is prevented from overheating. Normally, the printer increments the LF motor line by line at a rate which does not overheat the LF motor. However, if the motor is driven substantially continuously, overheating may occur. To prevent this, a first timer TM 1  is set to count a first time interval ti. The number of line feed increments is counted during t 1  to provide a first heat release signal P indicative of the heat generated by the motor. If P exceeds a prescribed value (i.e. if overheating occurs) a timer TM 2  is started. During the time that TM 2  is operative, the LF motor can only be incremented at a slower rate that would be correspondingly possible during the period ti, for causing cooling of the motor. A second heat release signal P is determined for the period t 2  of the time TM 2 . If the second heat release signal is less than a prescribed value the motor returns to normal operation under the control of timer TM 1 ; otherwise it is controlled for a further period under timer TM 2  to promote cooling.

Abstract: A semiconductor laser structure having the same advantages as a channeled substrate planar laser, but without the difficulties of fabrication associated with this structure. The structure in­cludes a substrate (10), a planar first cladding layer (14), a planar active layer (16), and a second cladding layer (18) in which a mesa region (22) is formed. A blocking layer (24) is formed over the second cladding layer (18) and electrical contact (26) is made through the blocking layer (24) in the region of the mesa (22). The blocking layer (24) functions to confine current flow in the mesa region (22) and to pro­vide index-guiding of light in the mesa region (22). Because of its simple geometry, the structure can be conveniently formed using a desirable fabrication process, such as metalorganic chemical vapor depo­sition (MOCVD). In one disclosed embodiment of the invention, the mesa (22') is broadened to include at least one intermediate ledge (28) on each side of a central pedestal. This reduces the abruptness of the change in effective index of refraction encountered by the laser light, and reduces astigmatism in the resultant beam.

Abstract: A wide area cordless telephone system covers a service area which is divided into a plurality of local areas to each of which belong a plurality of home position cordless telephones having multi-channel access capability. A plurality of access units are provided in each local area to define a plurality of access zones. A pre-dialing switching stage is provided for each local area to establish a connection between the access units and line terminals of a telephone switching system. Signals sent from any cordless telephone are received by a nearby access unit and applied to the pre-dialing switching stage. Each telephone transmits a registration request upon a manual command and, on receiving a response identifying a local area, returns an acknowlegement to identify the same local area as identified by the received response. On receiving a registration request, the pre-dialing switching stage transmits a response identifying the own local area through an access unit and assigns a reserved line terminal of the telephone switching system to a non-home position telephone if it is identified by the received request. On receiving an acknowledgement, the switching stage makes a registration of a telephone if the acknowledgement from it identifies the same local area as identified by the response.

Abstract: A device for characterizing the formation of a sheet material is described. The device comprises a basis weight sensor for measuring the basis weight of the sheet material as the material moves through the sensor and signal processing circuitry which receives a signal from the basis weight sensor indicative of the measured basis weight. The basis weight sensor includes a light source for directing a beam of light at the moving sheet and a light detector which detects the beam after it passes through the sheet. This detector produces a signal indicative of the intensity of the detected beam and transmits the signal to the signal processing circuitry. To calibrate the signal processing circuitry, a rotatable opaque wheel having a plurality of slots is positioned in the path of the light beam. The rotating wheel alternately blocks the light beam and allows the beam to pass through the slots to the detector. By rotating the wheel at a predetermined speed, the signal produced by the light detector is modulated at a predetermined frequency dependent upon the rotational speed of the wheel and the number of slots in the wheel. After calibration, an electromagnet rotates and holds the wheel in a position wherein the light beam passes, unobstructed by the wheel, through one of the slots.
